3.0
Conventions
3.1
Circuits
Refers to an actual electrical interface for initiating (detection), indicating (signal), and
releasing.
3.2
Zone
Is a logical concept for a Fire Alarm Protected Area, and will consist of at least one Circuit.
Often the terms Zone and Circuit are used interchangeably, but in this Manual the term Circuit
is used.
3.3
Display Points
There is a display point associated with every initiating and indicating circuit of the FR-320
LED Series fire panel. For an initiating circuit there are two LEDs for every display point: one
single color (amber) and one dual color (red/amber). For an indicating circuit there is only one
LED: one single color (amber), for every display point.
3.4
Wiring Styles
Initiating and indicating circuits are Class B (Style B and Y). Changing the initiating circuits to
Class A requires an ICAC-306 adder board which will convert SIX initiating zones from Class
B (Style B) circuits to Class A (Style D). This is done without penalizing the number of circuits,
which remains the same as in Class B (Style B). Changing the indicating circuits to Class A
requires an OCAC-302 adder board, which will convert TWO indicating zones from Class B
(Style Y) circuits to Class A (Style Z). Releasing circuits (Z) are Class B (Style B) only.
